US Extension Cord Suppliers

The maximum wattage that a US extension cord can handle depends on several factors, including the cord's length, gauge, and type. Generally, the longer the cord and the smaller the gauge, the less wattage the cord can handle.
As a rule of thumb, most indoor extension cords have a maximum wattage rating of around 1,625 watts (or 13 amps) and a maximum voltage rating of 125 volts. Outdoor extension cords may have a slightly higher wattage rating, but it's important to check the cord's specifications to ensure that it can handle the intended load.
It's important not to overload an extension cord beyond its rated capacity, as this can cause the cord to overheat and start a fire. Always check the manufacturer's specifications and use the appropriate cord for the intended device or appliance.

The length of a US extension cord can vary depending on the type, gauge, and intended use of the cord. In general, the length of a standard extension cord can range from 6 feet to 100 feet or more.
For indoor use, a shorter cord may be more practical, while longer cords are more commonly used for outdoor applications where power sources may be located farther away.
When selecting an extension cord, it's important to choose a length that is appropriate for the intended use and to avoid using a cord that is too long or too short for the job. It's also important to keep in mind that the longer the cord, the more voltage drop can occur, which can affect the performance of some devices. In general, it's best to choose the shortest cord possible that will reach the intended power source.

The main difference between a 2-prong and a 3-prong US extension cord is the number of prongs on the plug.
A 2-prong extension cord has two prongs on the plug, which are typically a hot wire and a neutral wire. These cords are ungrounded and are typically used with devices that don't have a ground pin on their plug, such as lamps or small appliances.
A 3-prong extension cord, on the other hand, has three prongs on the plug, which include a hot wire, a neutral wire, and a ground wire. The ground wire is an important safety feature that provides a path for electrical current to safely flow to the ground in case of a short circuit or other electrical fault. This can prevent electrical shocks and reduce the risk of electrical fires.
It's important to note that some devices may require a grounded 3-prong extension cord to operate safely. Always check the manufacturer's instructions and choose the appropriate extension cord for the device you're using. Additionally, never remove the ground pin from a 3-prong extension cord plug or use a 2-prong adapter with a 3-prong extension cord, as this can create a serious safety hazard.
